Field Testing of the FIFISH W6 NAVI Underwater Robot at the Port of Bar - Expert Support by INVAR-IVOŠEVIĆ Ltd. in Advanced Underwater Filming

Innovative Testing in the Heart of the Adriatic

On July 18, 2025, field testing of the FIFISH W6 NAVI underwater robot and accompanying equipment—procured by the Maritime Faculty of Kotor through the MARROBO project—was conducted in the waters of the Port of Bar.
The project, titled "Fostering the innovation capacities and skills for marine robotics deployment for monitoring and marine environment protection– MARROBO," is funded under the Interreg IPA Croatia-Bosnia and Herzegovina-Montenegro program and co-funded by the European Union.

Underwater surveys were carried out at three selected locations within the Port of Bar AD, capturing impressive footage of the sunken steam yacht “Rumija”, once owned by Prince and King Nikola I Petrović, which sank back in 1915.
